It allows undergraduate chemistry students to gain experience in the measurement of drug permeability coefficients, a key indicator used by the pharmaceutical industry to identify the ease of absorption of any new drug candidate. The experiment requires a diffusion cell, coated membrane, peristaltic pump and UV-Vis spectrophotometer. The method has been validated by determining the permeability coefficients for a selection of acidic, basic and non-ionizable drugs. Using this assay, it is possible to classify drugs as exhibiting high or low permeability in a fast, facile and reliable manner.","PeriodicalId":22396,"journal":{"name":"The Chemical Educator","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84921827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These reactions have important roles in synthetic chemistry; therefore, a wide range of experiments involving isotopic labeling or kinetic isotope effects were employed to establish their mechanistic pathways. The concepts introduced by these investigations are drawn together with an isotopic labeling study of the oxidation of urea with hypohalites. The two mechanisms proposed for this reaction have been described as a Hofmann rearrangement and a nitrogen analogue of the Favorskii rearrangement.","PeriodicalId":22396,"journal":{"name":"The Chemical Educator","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86149468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
